The Genuine Porsche Engine Crankcase Breather Kit - 471485 is a comprehensive set of products designed specifically for cars with Porsche engines. It includes four essential components that work together to regulate the air flow in the engine's crankcase. These components are designed to effectively remove any excess pressure or buildup of gases in the crankcase, ensuring optimal engine performance and longevity.

The first component included in the kit is a breather hose, which is responsible for directing the flow of air from the crankcase to the intake manifold. This helps to prevent any pressure buildup in the crankcase, which can lead to engine damage.

The second component is a breather valve, which is designed to regulate the flow of air through the breather hose. This valve ensures that the correct amount of air is being directed to the intake manifold, maintaining the proper balance of air and fuel in the engine.

The third component is a breather pipe, which connects the breather valve to the engine's crankcase. This pipe is specifically designed to withstand the high temperatures and pressures within the engine, ensuring its durability and longevity.

Finally, the kit includes a breather filter, which is responsible for filtering out any impurities or contaminants from the air before it enters the engine. This helps to protect the engine from any potential damage and maintain its overall performance.

Overall, the Genuine Porsche Engine Crankcase Breather Kit - 471485 is a crucial set of products for maintaining the health and performance of a Porsche engine. It is a must-have for any Porsche owner looking to keep their engine running smoothly and efficiently.
